Here you can find a tutorial how to get started with your CANduino v3.1. Please make sure that you really use the v3.1, because on v3 the CS_Pin was CS_Pin 8!
If you don't have a CANduino yet, you can buy one here: https://canduino.de
Before we can start with the program it is important to check if the jumper CAN_CS (on top next to the USB-C port) is connected to a soldering point. Only if this is connected, it is possible to address the mcp2515.
The following library must be installed before use: https://github.com/autowp/arduino-mcp2515/archive/master.zip
If your CANduino is at the end of the CANbus chain, it is mandatory to connect the CAN_T jumper (next to the CAN connector)!
So that the mcp2515 can be addressed it is important to set the following parameters:
MCP2515 mcp2515(10);
mcp2515.setBitrate("Your Bitrate", MCP_8MHZ);
In the examples folder you will find two code examples with which you have the possibility to send and receive CAN messages.
If the CANduino is not displayed, please download the driver for the CH340 which can be found here: http://www.wch-ic.com/downloads/CH341SER_ZIP.html
If you have the CANduino v3 with ATmega168PA the following board manager URL must be inserted in the programming environment (Arduino IDE). The bootloader is preinstalled: https://mcudude.github.io/MiniCore/package_MCUdude_MiniCore_index.json
Please use our instructions for v3 which you can find here: https://github.com/MassiveButDynamic/canduino-v3
